Modifications around the hydroxamic acid chelating group of fosmidomycin, an inhibitor of the metalloenzyme 1-deoxyxylulose 5-phosphate reductoisomerase (DXR)

Fosmidomycin derivatives in which the hydroxamic acid group has been replaced by several bidentate chelators as potential hydroxamic alternatives were prepared and tested against the DXR from Escherichia coli. These results illustrate the predominant role
Iron tricarbonyl stabilized pentadienyl cation as initiator for cascade polycyclizations: A diastereoselective entry into octahydrophenanthrenes

A new example is provided of completely diastereoselective polycyclization, affording the octahydrophenanthrene framework. Generation of an iron tricarbonyl stabilized pentadienyl carbocation is the triggering event of the cascade reaction. The carbocation is generated by anchimerically assisted regiospecific protonation of a double bond adjacent to the iron tricarbonyl diene moiety. Tetrafluoroboric acid ether complex appears to be the optimum reagent, affording good yields, even under catalytic conditions.
Hydroxyl-Directed Regioselective Monodemethylation of Polymethoxyarenes
Lal, Kasturi,Ghosh, Subrata,Salomon, Robert G.
, p. 1072 - 1078 (2007/10/02)
Methoxyl groups ortho to β-hydroxyethyl or γ-hydroxypropyl substituents in polymethoxybenzene derivatives were regioselectively demethylated with sodium thioethoxide in N,N-dimethylformamide.Methoxydihydrobenzofurans or methoxychromans were produced by cyclization of the monodemethylated β-hydroxyethyl or γ-hydroxypropyl derivatives, respectively.
